Maximum Drawdown (MDD)

Maximum drawdown (MDD) is the largest drop in the value of an investment or portfolio from its highest point to its lowest point during a specific period. It represents the worst-case loss an investor could face during adverse market conditions.

Understanding Maximum Drawdown

Maximum drawdown measures how much an investment can lose during its worst phase. It shows the largest drop in the value of an asset from its highest point to its lowest point within a specific period.

This measure is commonly used to compare the risk levels of different stocks or mutual funds before deciding where to invest.

A fund with a smaller maximum drawdown is less risky during market downturns and is a safer choice for conservative or risk-averse investors. On the other hand, a fund with a larger drawdown might offer higher returns but comes with greater risk, making it more suitable for aggressive investors.

A fund with a smaller maximum drawdown indicates it is less risky during market downturns, making it a more stable choice for investors.

How is Maximum Drawdown Calculated?

Maximum drawdown provides a percentage measure of loss. Here is the formula

• Peak Value: The highest value an investment or portfolio reaches during a specific time period.
• Trough Value: the lowest value the investment falls to after reaching the peak value.

Let’s understand how the maximum drawdown is calculated for a portfolio where an initial investment of ₹1,00,000 grows to ₹1,50,000, then falls to ₹80,000, and later recovers to ₹1,20,000.

So here,

Initial Investment = ₹1,00,000

Peak Value = ₹1,50,000

Trough Value = ₹80,000

Recovery Value = ₹1,20,000

• Find the drop from the peak: Peak Value – Trough Value = ₹1,50,000 – ₹80,000 = ₹70,000
• Divide the drop by the peak value: ₹70,000 / ₹1,50,000 = 0.4667
• Convert to percentage: 0.4667 × 100 = 46.67%

The maximum drawdown for this portfolio is 46.67%, meaning the portfolio lost almost half of its value at its worst point after reaching the peak.

A drawdown of 46% shows that the portfolio has experienced a significant loss from 1,50,000 to 80,000. For an investor, it shows the potential worst-case scenario if the portfolio were to hit such a low point again.

Significance Of Drawdown

Understanding the significance of drawdowns helps investors assess the risk involved in their investments. It gives a clear picture of how much value a portfolio can lose during tough times, making it an essential factor in decision-making.

Maximum Drawdown As a Risk Assessment Tool

Maximum drawdown shows the biggest loss an investor might face during a certain time. It helps understand the risk of an investment in tough market conditions. Investments with smaller maximum drawdowns are generally considered less risky, while those with larger drawdowns indicate higher risk and volatility. This helps investors choose portfolios that align with their risk tolerance.

For example, last year, the Nifty 50 index reached its all-time high of 26,277 on September 27 and dropped to its lowest value of 24,000 by the end of October. Using these values, we can calculate the drawdown as follows:

Maximum drawdown (%) = [(26,277.35 – 24,000) / 26,277.35] × 100 ≈ 8.67%

This means that during the worst phase, the index fell by around 8.67% from its peak.

If investors plan to start investing in the Nifty 50 today (January 20), they should be prepared for the possibility of an 8% loss in their portfolio in a similar worst-case scenario. Understanding this helps set realistic expectations about potential short-term risks.

Drawdown As a Tool For Investment

Maximum drawdown helps compare similar investments by showing the risk-adjusted returns. Investors can use this information to pick options that match their risk tolerance. For example, a young investor may accept higher drawdowns to benefit from growth opportunities, while a risk-averse investor might prefer options with lower drawdowns for more stability.

Use of Drawdown in Portfolio Management

Drawdown is an essential tool in portfolio management. Portfolio managers and risk analysts use it to gauge the risk involved in the investment. This is done by:

• Allocating funds between high-risk and low-risk assets, and
• Stress testing portfolios during volatile market conditions

Drawdown Guides Allocation Between High-Risk and Low-Risk Assets:

Drawdown helps portfolio managers allocate investments between high-risk assets like equity and derivatives (F&O) and low-risk assets. They design the portfolio based on the investor’s financial goals and their ability to handle losses during market downturns, ensuring a balance between risk and stability.

For instance, if an investor observes that equities have a higher maximum drawdown compared to bonds, they might allocate a larger portion to bonds for stability, especially if they have a low risk tolerance.

Stress-Testing Portfolios During Volatile Market Conditions

Stress testing is done on the portfolios to see how well they perform in extreme market conditions. Drawdown is one of the key metrics for stress testing portfolios to understand how they might perform in challenging times. By analysing historical drawdowns, portfolio managers can predict potential losses and prepare for similar scenarios in the future.

For example, if a portfolio lost 20% of its value during a market crash, managers might use strategies like diversification or hedging to reduce the chances of such big losses happening again in the future.

What is a ‘Good’ or ‘Bad’ Maximum Drawdown?

Maximum Drawdown (MDD) measures the largest decline in the value of an investment from its peak to the lowest point over a specific period. It reflects the potential risk and volatility of an investment. Understanding MDD helps investors evaluate how much loss they might face during market downturns.

Good Maximum Drawdown

A good MDD is relatively small, indicating that the investment experiences minor declines even during market stress. This suggests lower risk and higher capital preservation. For example:

• If a mutual fund has a maximum drawdown of 5%, it means that at its worst, the fund’s value fell by only 5% from its peak, which is considered safe and stable.

Bad Maximum Drawdown

A bad MDD is large, showing that the investment can suffer significant losses during downturns. This indicates a higher risk and potential stress for the investor. For example:

• If an equity fund experiences a maximum drawdown of 40%, it implies a severe drop in value, which could be unsuitable for risk-averse investors.

A “good” or “bad” MDD depends on the investor’s risk tolerance. Lower drawdowns are generally better for conservative investors focused on capital preservation, while higher drawdowns may be acceptable for those seeking higher returns with greater risk.

Major Difference between Maximum Drawdown and Sharpe Ratio

Conclusion

Maximum drawdown is a crucial tool for understanding the risks of investments. It helps investors see how much they could lose during tough times and make better decisions about where to put their money.

By looking at drawdown, investors can choose investments that match their goals and how much risk they are comfortable with. It also helps compare different options to pick the ones that are more stable and less risky.

For portfolio managers, maximum drawdown helps to plan asset allocation and test how portfolios might handle bad market conditions. It ensures investments are managed in a way that balances risk and reward, helping both investors and managers work towards long-term success.
